Swedish Confederation of Professional Employees), by Svenska  
Naturskyddsforeningen (The Swedish Society for Nature Conservation),  
and by Statens Energimyndighet (The Swedish National Energy  
Administration).  
Approval requirements cover a wide range of issues: environment,  
ergonomics, usability, emission of electric and magnetic fields, energy  
consumption and electrical and fire safety.  
The environmental demands impose restrictions on the presence and use  
of heavy metals, brominated and chlorinated flame retardants, CFCs  
(freons) and chlorinated solvents, among other things. The product must be  
prepared for recycling and the manufacturer is obliged to have an  
environmental policy which must be adhered to in each country where the  
company implements its operational policy.  
The energy requirements include a demand that the computer and/or  
display, after a certain period of inactivity, shall reduce its power  
consumption to a lower level in one or more stages. The length of time to  
reactivate the computer shall be reasonable for the user.  
Labeled products must meet strict environmental demands, for example, in  
respect of the reduction of electric and magnetic fields, physical and visual  
ergonomics and good usability.  
On the Back page of this folder, you will find a brief summary of the  
environmental requirements met by this product. The complete  
environmental criteria document may be ordered from:

Environmental requirements  
Flame retardants  
Flame retardants are present in printed circuit boards, cables, wires,  
casings and housings. Their purpose is to prevent, or at least to delay the  
spread of fire. Up to 30% of the plastic in a computer casing can consist of  
flame retardant substances. Most flame retardants contain bromine or  
chloride, and those flame retardants are chemically related to another  
group of environmental toxins, PCBs. Both the flame retardants containing  
bromine or chloride and the PCBs are suspected of giving rise to severe  
health effects, including reproductive damage in fish-eating birds and  
mammals, due to the bio-accumulative* processes. Flame retardants have  
been found in human blood and researchers fear that disturbances in  
foetus development may occur.  
The relevant TCO'99 demand requires that plastic components weighing  
more than 25 grams must not contain flame retardants with organically  
bound bromine or chlorine. Flame retardants are allowed in the printed  
circuit boards since no substitutes are available.  
Cadmium  
Cadmium is present in rechargeable batteries and in the color-generating  
layers of certain computer displays. Cadmium damages the nervous  
system and is toxic in high doses. The relevant TCO'99 requirement states  
that batteries, the color-generating layers of display screens and the  
electrical or electronics components must not contain any cadmium.  
Mercury  
Mercury is sometimes found in batteries, relays and switches. It damages  
the nervous system and is toxic in high doses. The relevant TCO'99  
requirement states that batteries may not contain any mercury. It also  
demands that mercury is not present in any of the electrical or electronics  
components associated with the labeled unit.  
* Bio-accumulative is defined as substances which accumulate within living  
organisms  
 
CFCs (freons)  
The relevant TCO'99 requirement states that neither CFCs nor HCFCs may  
be used during the manufacture and assembly of the product. CFCs (freons)  
are sometimes used for washing printed circuit boards. CFCs break down  
ozone and thereby damage the ozone layer in the stratosphere, causing  
increased reception on earth of ultraviolet light with e.g. increased risks of  
skin cancer (malignant melanoma) as a consequence.  
Lead**  
Lead can be found in picture tubes, display screens, solders and capacitors.  
Lead damages the nervous system and in higher doses, causes lead  
poisoning. The relevant TCO´99 requirement permits the inclusion of lead  
since no replacement has yet been developed.  
** Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.  
 
Operation Instructions  
Thank you for purchasing this monitor, a high-resolution multi-scan color  
monitor.  
Please read this guide thoroughly before installation.  
FCC RADIO FREQUENCY INTERFERENCE STATEMENT  
WARNING: (FOR FCC CERTIFIED MODELS)  
This monitor has been tested and found compliant with the limits for a  
Class B digital device, pursuant to part 15 of the FCC Rules. These limits  
are designed to provide proper protection against harmful interference to a  
residential installation. This monitor generates, uses, and can radiate radio  
frequency energy. Harmful interference to radio communication may be led  
as a result if it‘s not properly installed and used. However, there is no  
guarantee that interference will not occur in a particular installation. If this  
monitor does cause serious interference to radio or television reception,  
resetting the monitor may determine it. Moreover, users are encouraged to  
correct interference by doing one or more of the following:  
Reorient or relocate the receiving antenna.  
Move the monitor and the receiver further away from each other.  
Connect the monitor into an outlet on a circuit different from that to  
which the receiver is connected.  
Consult your local dealer or an qualified technician.  
FCC Warning:  
To assure a continued FCC compliance, a user must use a grounded  
power supply cord and the provided shielded video interface cable with  
bonded ferrite cores. Also, any unauthorized changes or modifications to  
this monitor would void the user‘s authority to operate this device.  
Note: If necessary, shielded interface cables and AC power cord must be  
used to meet the emission level limits.

Care and Maintenance  
Care  
Avoid exposing your monitor directly to sunlight or other heat source. Place your  
monitor away from the sun to reduce glare.  
Put your monitor in a well ventilated area.  
Do not place any heavy things on top of your monitor.  
Make certain your monitor is installed in a clean and moisture-free area.  
Keep your monitor away from magnets, motors, transformers, speakers, and TV  
sets.  
Note  
Move the LCD out of the package and take off the plastic bag and Polystyrene Foam.  
Pull the base from Parallel versus Panel to Vertical.  
Adjust the Panel within 0 degree leaning forward and 20 degree leaning  
backward. You must bend harder to exceed 20 degree backward but this range  
is for packing the unit to a small size for storage only.  
Safety Tips:  
If smoke, abnormal noise or odor came out from your monitor, caution you  
should remove the power cord immediately and call your service center.  
Never remove the rear cover of your monitor cabinet. The display unit inside  
contains high-voltage parts and may cause electric shock to human bodies.  
Never try to repair your monitor yourself. Always call your service center or a  
qualified technician to fix it.  
Troubleshooting  
No power  
Make sure A/C power cord is securely connected to the power adapter and the  
power supply is firmly connected to the monitor.  
Plug another electrical device into the power outlet to verify that the outlet is  
supplying proper voltage.  
Make sure all signal cables are installed.  
Power on but no screen image  
Make sure the video cable supplied with the monitor is tightly secured to the  
video output port on back of the computer. If not, tightly secure it.  
Adjust brightness.  
9
 
Wrong or abnormal colors  
If any colors (red, green, blue) are missing, check the video cable to make sure  
it is securely connected. Loose or broken pins in the cable connector could  
cause an improper connection.  
Connect the monitor to another computer.  
According to WEEE regulation , this monitor can't be handled as  
normal trash in Europe when it is out of usage. Please refer to the  
recycle information from our website to handle it.
